ARLINGTON, Texas (AP) — Tony Romo threw for 198 yards with two long touchdowns to Dwayne Harris while playing only the first quarter, and Dallas beat St. Louis.

In what was supposed to be Romo's most extensive action of the preseason, he showed more than enough to coach Jason Garrett in three offensive drives, even with his top three pass-catchers hurt and not playing.

Romo completed 9-of-13 passes, including a 61-yard TD after Harris got behind the Rams defense. On the next possession, Harris split two defenders after making the catch for a 38-yard score.

Dallas (2-1, No. 15 in the AP Pro32) wraps up its preseason at home against Miami on Wednesday, a week before opening the regular season at the New York Giants. The Rams (1-2, No. 28) play Baltimore on Thursday.

SAINTS 34, TEXANS 27

NEW ORLEANS (AP) — Matt Schaub and Drew Brees looked sharp in a high-scoring first half, and Joe Morgan's touchdown catch late in the fourth quarter lifted New Orleans over Houston.

Schaub completed 15-of-18 passes for 194 yards and a touchdown, but three turnovers by Houston (2-1, No. 4 in the AP Pro 32) helped the Saints (2-2, No. 9) stay close despite two fumbles of their own.

Brees was 17 of 25 for 179 yards, including TD tosses to Lance Moore and Jimmy Graham.

ORCHARD PARK, N.Y. (AP) — Receiver Antonio Brown scored two touchdowns in leading Pittsburgh to a preseason rout of Buffalo.

Ben Roethlisberger shook off a slow start by engineering an 11-play, 98-yard touchdown drive for the go-ahead score with a 6-yard pass to Brown at the end of the first half. Brown then opened the second half with a 39-yard touchdown catch from backup Byron Leftwich in helping the Steelers (No. 7 in the AP Pro32) improve to 2-1.

Fred Jackson scored on a 1-yard plunge, and high-priced defensive end Mario Williams had two sacks for the Bills (No.9), who dropped to 0-3. The Bills' starting offense sputtered in producing just one score despite five of seven drives into Steelers territory.

RAIDERS 31, LIONS 20

OAKLAND, Calif. (AP) — Matthew Stafford threw for 68 yards until leaving with an injury to his non-throwing hand in Detroit's loss to Oakland.

Defensive end Dave Tollefson drove Stafford to the ground after an incomplete pass in the second quarter. Team trainers wrapped Stafford's left hand in heavy bandages and a brace on the sideline. Shaun Hill took over on Detroit's next possession.

Oakland (1-2) sidelined several more Detroit (1-2) players.

Cornerback Bill Bentley departed with a shoulder injury and Chris Houston with a left ankle injury in the first half for the Lions (tied for No. 11 in the AP Pro32). Running back Kevin Smith also left with a right ankle injury and trainers wrapped bandages around Mikel Leshoure's midsection after his final run.

The Raiders (No. 23) remained mostly injury free — one of the bright spots from the starting unit — and relied on backup Terrelle Pryor to provide the spark. He went 3 for 5 for 137 yards and two touchdowns. He also ran for 90 yards and a score on five carries.
